As per my knowledge in computer your definition is right.

Shared mean memory can be used together by system or by gpu but in this case i dont know which one take priority. Lets vadonka answer my questiom

For other ramhack there is no way gpu can use that portion of memory and causing some trouble like unable to reboot etc
[LG Optimus 2x] Wing_Zero85:
Yes. Gingerbread is not dual-core optimized, and you have cutted off even more the power of the second core?

I mean, I'm glad of your work, and thanks for your hard work, but this "feature" first of all doesn't help to prevent battey drain: I've the same uptime with cm7 stock kernel or ethana, btw in some games (like shadowgun) I'm noticing little stuttering with your kernel than the stock one.

Regarding UI usage, your kernel is very smooth and better that CM stock one, but on high-load-applications i think it's better the stock one.
[LG Optimus 2x] Barnabe619:
Would it be better to have the second core always on (Except in True Idle) but at a frequency much lower ?

Instead of having 1 core @ 1Ghz

we would have 2 cores @ 500 Mhz
[LG Optimus 2x] silentmelodies:
I think you don't get his point. What he is saying is that GB can't really distribute the work properly between cores, and having the second core run at higher speeds won't really do any significant performance boost. So that's why he's lowering the second core speed to a speed fast enough to ensure smooth operation and multitasking, but not necessarily high to waste too much power. You may not notice much difference in battery drain, but that's because you didn't do a very specific battery test (for example making comparison doing the exact same activities with the same conditions, variables, ect). There is a clear difference theoretically, it just isn't very noticeable.

As to performance differences, you most likely became unsubjective because you got the benchmark results. The difference is really small, so there shouldn't be that much of a performance difference too. Plus Shadowgun isn't really that CPU intensive. It loads most content of the map beforehand, so there isn't much heavy lifting done afterwards. The stuttering must have been because other factors. In my own experience playing Shadowgun, there isn't any lag at all using both stock CM and ETaNa kernel.

And lastly, it doesn't make sense that the kernel can provide smooth UI but poorer performance elsewhere.
[LG Optimus 2x] spica1234:
Its not good to keep 2nd core always on. Its most battery hungry, i mean 2nd core. 2 core @500 will consume more battery rather than 1 @ 1ghz.nothing eats as much power like 2nd core not even oced gpu or oced sdram:) and main nothing you wont notice noticeable performance boost in realtime tasks:)
[LG Optimus 2x] Barnabe619:
I didn't know this second core needed so much power, thank you !

I tried the old wireless drivers and the WiFi don't open at all.
[LG Optimus 2x] pastime1971:
i just remembered that nvidia claimed 2 @ 500 consumes less power than 1 @ 1000, as power consumption follows P = N * V^2/R, and V is proportional to f. i guess that is not true in practice, at least not on GB.

I was playing with my phone but I felt it was hot.... My CPU was at 54°C I think it's really, really too hot. .. :s
[LG Optimus 2x] vadonka:
Mr. Spica

can you allow me to assimilate your OTF pack in my kernel?

it can be help the second core optimization

and the OTF available in a cm7/miui kernel too

im not using your very own work without your permission

im waiting for your answer :)
[LG Optimus 2x] vadonka:
thx :)

yes, i noticed that the spica.h file is missing from the source. i guess i wait while you released the source :)
[LG Optimus 2x] spica1234:
one more library file is also missing which is more important then spica.h, all functions are defined there so w/o functions all codes becomes inactive:p hehe, the main reason was if a kid compiler adds the codes blindly or removes initial lines blindly then he can blame me that spica's code is dangerous, you know about who kid compiler I'm talking :p hehe kidding

Main reason for it was UV (-25/-50/-100)is not at all helping in power consumption, plus it associate more issue like freeze and else
[LG Optimus 2x] vadonka:
i have absolutely no idea :)

about the uv: i agree with you, i try many combination of uv but every time it can caused bsod for some users. so im stay close to the stock voltages, everybody can do the uv if need it.

+-10mV dont change the battery life but might be affect the stability. so its better to keep the voltages in a higher level.
[LG Optimus 2x] Schmeichel1:
I'm testing your kernel on standard MIUI PL and it works great ... I'm waiting to test new one :) i UV like in your main post and all works fine without any problem ... only problem for me is SWAP I don't have SWAP partition and only use swap file and it causes problem when Mounting USB ... is swap needed?

plant vs zombie on mine can't work on cm7 KANG with stock kernel, i think it's not because the kernel problem.
[LG Optimus 2x] rskyline:
So is a hardware problem maybe because i can't play it with this and you can't with stock

I've tried again, and with temasek's last build. With stock it runs any game. With this plants vs zombies freeze... i like this kernel I'm only trying to help!

[LG Optimus 2x] antec123:
nah, it's not either hardware problem. because when i play pvz on stock rom it can play nicely, and with older CM7 it can too. but when i switch to cm7 kang, it can't play anymore :( so i think it's about the software it self needs to update. anyway i already dumped it since i can play on my pc :D so not big deal

[LG Optimus 2x] steindani:
hungry phone

Vadonka!

The kernel is really nice, thanks for the development! It's good to see another Hungarian around here.

However I have a little problem: when the screen is off, the phone only uses 1-5 / 10-20 mAh. But when I'm lightly using the phone (checking mail, reading twitter/facebook), the consumption can go up to 500mAh, which is not really good.

Is it normal? As I can recall, some weeks ago it was better. I'm using WiFi Power TX and the processor is clocked ~1.1GHz. The screen brightness is kinda low. Using the newest Kang and kernel (shared).

Is it common, and every O2x eats this much during lightweight usage?

Thanks!
[LG Optimus 2x] alediniz:
Me too, what's wrong with our phones?

I tried to flash a New BB, impossible: smartflash give me an error. I don't think i'ts because of the kernel, however, if you've got an idea..

[LG Optimus 2x] nikolav75:
There is indeed a problem somewhere. After my last post I updated to temasek's KANG build P204-60 + Feb8 ETaNa 0MB. Before that I was with temasek's KANG build P204-57.

When I opened the marked it found some updates and when I tried to update, the result was FC. The same with manual update or simply with installing some apps.

I restarted, deleted cash partition (with the touchCWM) and after the reboot everything seems to be OK now.

i read the posts guys just i dont have time to answer everybody :)

im fixed some things, for example the touchcwm cache clean problem, and a few others, and i making some adjustment.

That's strange. CM7 Kang 60 + ETaNa_REV1_32S and Sonic is working perfectly for me.

Nope, i'm wrong... It ran fine just firs two or three times, now it is freezing after Sega logo, on a white screen.

Peggle and PvZ also freeze on a PopCap logo. On a stock CM7 kernel all games work perfect.

By the way, it looks like it's a media problem.

After game freezes logcat is full with such lines:

The TouchCWM has a problem with wiping cache (or to be preciseley - with rebuilding it) - I've read a couple posts of people with market problems due to this. I'd use the "old" recovery till this gets fixed.
[LG Optimus 2x] vadonka:
the touch cwm cache clean problem is fixed in the latest version
[LG Optimus 2x] tonyp:
Ah you beat me - just wanted to edit my post. :D

But we should be aware that it's only getting wiped and rebuild correctly when installing your kernel - when we wipe cache manually via CWMTouch it will still fail. So don't wipe cache in CWMTouch!

I've seen a flashable ZIP somewhere which will only wipe cache as a workaround.
[LG Optimus 2x] vadonka:
im change the cache wipe process to a simplier way:

remove every file from the cache partition and then do a simple fsck. this method doesn't hurt the filesystem.

the previous method recreate the whole cache partition and this may be broken in the touchcwm.

Strange, never had any problem with touchCWM, not even when I wipe cache and dalvik in tCWM.

[LG Optimus 2x] vadonka:
there is no such user who you suggest :) at least the xda saying this, or im a noob :D

by the way im succesfully separate the tweak init script and the parameters file, so its no need to modify the init script anymore. the parameter file stored on the data partition. in the future updates the installer respect the present parameter file and dont overwrite, so if you have a custom settings you will not loose this.

i also merged some updates to the kernel, if i have time i will release today, if not then delayed to tomorrow :)

note: this parameter file contained only the parameter definition and commented lines, basicly i need an app what can be read this file and display the parameters and allow to change that, then write back to the parameter file.

I believe the issue with Sonic 4 and the Popcap games is that the way the Stock G2x ROM accesses memory. In the stock rom it allocates 128MB of Ram to the GPU and on some ROMs I notice that the RAM allocated to GPU is dropped to 96MB, so this likely is whats causing the issue with these games expecting to have access to 128mb but only getting access to 96mb, so they either freeze or crash. I'm also getting this problem with Dungeon Defenders.
